Security analysis of network traffic using behavioral signatures
Barabas, Maroš ; Hujňák,, Petr (referee) ; Zelinka,, Ivan (referee) ; Hanáček, Petr (advisor)
This thesis focuses on description of the current state of research in the detection of network attacks and subsequently on the improvement of detection capabilities of specific attacks by establishing a formal definition of network metrics. These metrics approximate the progress of network connection and create a signature, based on behavioral characteristics of the analyzed connection. The aim of this work is not the prevention of ongoing attacks, or the response to these attacks. The emphasis is on the analysis of connections to maximize information obtained and definition of the basis of detection system that can minimize the size of data collected from the network, leaving the most important information for subsequent analysis. The main goal of this work is to create the concept of the detection system by using defined metrics for reduction of the network traffic to signatures with an emphasis on the behavioral aspects of the communication. Another goal is to increase the autonomy of the detection system by developing an expert knowledge of honeypot system, with the condition of independence to the technological aspects of analyzed data (e.g. encryption, protocols used, technology and environment). Defining the concept of honeypot system's expert knowledge in the role of the teacher of classification algorithms creates autonomy of the~system for the detection of unknown attacks. This concept also provides the possibility of independent learning (with no human intervention) based on the knowledge collected from attacks on these systems. The thesis describes the process of creating laboratory environment and experiments with the defined network connection signature using collected data and downloaded test database. The results are compared with the state of the art of the network detection systems and the benefits of the proposed approximation methods are highlighted.

Source Code Metrics for Quality in Java
Sherstobitov, Vladyslav ; Dvořák, Tomáš (referee) ; Křivka, Zbyněk (advisor)
Pro kontrolu a zlepšovaní kvality zdrojového kódu musí být zaveden systém, který se skládá z kvantitativních metrik a jejich analýzy. S použitím metrik kvality softwaru, které reprezentují, jak dobře je zdrojový kód napsán, lze hodnotit zdrojový kód. Na základě tohoto hodnocení může kód splňovat nebo nesplňovat stanovená kritéria, která mohou být použita pro mnohá účely. Daný výzkum prezentuje program vyvinutý na základě identifikovaných vlastností kódu a souvisejících metrik, metod používaných při tvorbě programu a výsledků testů založených na projektech s otevřeným zdrojovým kódem.

Source Code Metrics for Quality in Java
Sherstobitov, Vladyslav ; Burget, Radek (referee) ; Křivka, Zbyněk (advisor)
Aby bylo možné kontrolovat a zlepšovat kvalitu kódu, musí být zaveden systém, který se skládá z kvantitavních metrik a jejich analýzy. S použitím metrik kvality softwaru, které nejlépe reprezentují, jak dobře je zdrojový kód napsán, lze hodnotit zdrojový kód. Na základě tohoto hodnocení může kód splňovat nebo nesplňovat stanovená kritéria, která mohou být použita pro mnohé účely. Daný výzkum prezentuje program vyvinutý na základě identifikovaných vlastností kódu a souvisejících metrik, metod používaných při tvorbě programu a výsledků testů založených na open-source projektech.

Detection of plagiatorism in software projects in the BDS course
Szymutko, Marek ; Přinosil, Jiří (referee) ; Šeda, Pavel (advisor)
Plagiarism is a widespread problem, which can be fought by prevention or detection methods. This thesis contains a summary of plagiarism detection methods through automated means. To parse source code, an open-source abstract syntax tree compiler was employed. The functionality of this compiler was demonstrated in this thesis. To reduce the mutual visibility of students’ projects, a proposal for the submission process was created. GitLab cloud service was employed for this purpose. Initialization of these students’ spaces is performed via Bash scripts. Other scripts to archive and create spaces for groups of students in the GitLab service were also created. A similarity-detecting tool was created in Python programming language. This tool was specialized to be employed in the subject BPC-BDS for the detection of plagiarism in students’ assignments written in Java or Python. It can also be used in other subjects though. For similarity detection, numerical metrics and abstract syntax trees were used. The comparison output of the projects and their individual parts is represented with integer value and outputted into a tabular file of the format xlsx. This thesis also summarizes the strengths and weaknesses of the implemented solution and lists problems that were encountered in the process of implementation. A case study about plagiarism in the subject BDS in the academic year 2022/2023 is also included in this thesis.
